Configuring exif-3000.0.0... Warning: No 'build-type' specified. If you do not need a custom Setup.hs or ./configure script then use 'build-type: Simple'. setup: Missing dependency on a foreign library: * Missing (or bad) header file: libexif/exif-data.h * Missing C library: exif This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. If the header file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. Failed to install exif-3000.0.0 cabal: Error: some packages failed to install: exif-3000.0.0 failed during the configure step. The exception was: ExitFailure 1 photoname-3.0.1 depends on exif-3000.0.0 which failed to install.
